packagecloud with apt-mirror

I dont have access direct to https://packagecloud.io/gitlab/gitlab-ce/debian, we use a apt-mirror. When i'm config the mirror with: deb https://packagecloud.io/gitlab/gitlab-ce/debian wheezy main deb-amd64 https://packagecloud.io/gitlab/gitlab-ce/debian wheezy main THe acces failed with this issue:

cannot open packagecloud.io/gitlab/gitlab-ce/debian/dists/wheezy/main/binary-i386/Packages.gz: No such file apt-mirror: can't open index in proceed_index_gz at /usr/bin/apt-mirror line 451.

any idea to use apt-mirror?

thx
